llustration labeled u201cartistu2019s conceptu201d at right bottom corner. At left bottom corner, a partially illuminated, lemon-shaped exoplanet appears against a black background. This planet is most brightly illuminated at its elongated tip on its right side. On the left side, which is wider, the planet trails off into the darkness of the background. The planet is colored in varying, mottled shades of red, light pink, and fuchsia. Most of the pink occurs closest to the tip, while most of the fuchsia is at the top and bottom edges. At right top corner, a white beam emanates diagonally, oriented from 10 ou2019clock to 4 ou2019clock, from either side of a small, glowing, white star.

An illustration of a young planet with a surrounding disk of dust and gas potentially forming moons. The planet, which appears dark red, is shown at lower right, circled by a cloudy, clumpy reddish orange-colored disk. The host star appears at upper left, and glows yellow, with its own reddish disk of debris. The disk that surrounds the planet takes up about half the illustration. The black background of space is speckled with stars. At the bottom of the illustration, graphics of molecules are listed in the following order: diacetylene, hydrogen cyanide, propyne, acetylene, ethane, carbon dioxide, benzene. The words Artist’s Concept appear at upper right.

$Gaseous yellow-orange filaments look like a rose seen from the side and tilted slightly from upper left to lower right, slightly higher than the center of the frame. Extending from the rose to upper left and lower right are gaseous outflows that appear as red lobes that have an overall shape of tall, narrow triangles with rounded tips. Each red triangle is made up of wavy, irregular lines. Dozens of stars are scattered across the field. One particularly bright white star with eight diffraction spikes is located at the top of the yellow rose. Another bright blue star with even more prominent diffraction spikes is to its lower left. The background of space is black.$
